Look at the ANOVA table. These are the results of an experiment that was done to test whether C (soil carbon) would differ after various methods of site prepartation before tree seedlings were planted. To measure carbon in the soil, the 0-5 cm and 6-10 cm topsoil depths were sampled and analyzed for C. Thus, there were 2 depths, 3 treatments sampled about 26 years after site prepartation occured. a. Explain the degress of freedom listed in the ANOVA table. b. There are three main sources of variation in an ANOVA. What are they (list and define them completely)?
Binge sample After hearing of Exercise 24’s nationalresult that 44% of students engage in binge drinking(5 drinks at a sitting for men, 4 for women), a professorsurveyed a random sample of 244 students and found that96 of them admitted to binge drinking in the past week.Should he be surprised at this result? Explain.
Women athletes at a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 38 women athletes at the school showed that 23 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 1% level of significance.
The degrees of freedom for the F test for the One-Way ANOVA depends on: Group of answer choices total sample size and the number of groups total sample size number of groups magnitude of the variance
Information regarding the ACT scores of randomly selected samples of students in three different majors is given in the table to the right. All three samples come from normally distributed populations. At a 5% significance level, test if there is a difference in the average ACT score across the three majors. -provide an ANOVA table
A random sample of 200 Gold accounts at Top Bank showed that 28 were overdrawn. When 300 Silver accounts at the same bank were randomly checked, it was found that 36 were overdrawn. Can the bank manager conclude that there is an equal proportion of Gold and Silver account holders who were overdrawn? Test this hypothesis at a 5% level of significance. Let Gold account =n1 and Silver account = n2 Critical value at 10% level of significance:1.645 Critical value at 5% level of significance:1.96 Critical value at 1% level of significance:2.576 Calculate the test stat and conclusion State the decision rule State the null hypothesis State the alternative hypothesis
Information regarding the ACT scores of randomly selected samples of students in three different majors is given in the table to the right. All three samples come from normally distributed populations. At a 5% significance level, test if there is a difference in the average ACT score across the three majors. (ANOVA test)
Eleven percent of the products produced at a factory over the past several months have failed to conform to specifications. The factory modifies the process in an attempt to reduce the rate of nonconformities. In a random sample of 225 items from a trial run, the modified process produces 12 nonconforming items. Do these results provide convincing evidence that the modification is effective? Find the test statistic for this hypothesis test.

researcher claims that not more than 65% officers in the public offices come on time in their offices. A random sample of 60 officers was taken on a random working day, It was observed that 37 officers were in time Test the claim of the researcher at 5% level of significance.
Assume that a simple random sample has been selected from a normally distributed population. Identify the null hypothesis, alternative hypothesis, test statistic, P-value (or range of P-value), critical value(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Technology is dramatically changing the way we communicate. In 1997, a survey of 880 U.S households showed that 149 of them use e-mail. Use those sample results to test the claim that more than 15% of U.S. households use e-mail. Use a 0.01 significance level.
A car manufacturer operates 24 hours using two shifts, day and night shifts. The manufactured cars sometimes have defects. Random samples of cars manufactured during the two shifts were collected and examined for defects. shift day night sample size 500 800 defective in the sample size 15 21 Test the hypothesis that there is no significance difference in the number of defects between day and night shifts at the 5% level of significance.
